Oceanic hotspot systems arise where mantle plumes ascending from deep within the Earth penetrate oceanic lithosphere, generating magmatism that forms volcanic islands, seamount chains and submarine ...

A new study was recently published in Nature Astronomy that concluded known geochemical processes cannot explain the levels of methane measured by the Cassini spacecraft on Saturn's frigid moon ...

The formation of Earth’s earliest continental crust during the Archean eon (4.0–2.5 Ga) reflects a complex interplay of mantle melting, magmatic differentiation and crustal recycling. Partial melting ...

Washington, DC-- New work from a team including Carnegie's Christopher Glein has revealed the pH of water spewing from a geyser-like plume on Saturn's moon Enceladus. Their findings are an important ...

Second, the valley's high altitude allows the researchers to study geochemical processes in a cold climate considered to be a potential "hot spot" of precursors to rising global temperatures. "Climate ...

Ancient limestone towers emerge from Mono Lake, shaped by time and a unique geochemical process. Towering limestone formations, Tufas, rise from Mono Lake, sculpted over thousands of years by a unique ...

New work has revealed the pH of water spewing from a geyser-like plume on Saturn's moon Enceladus. Their findings are an important step toward determining whether life could exist, or could have ...
